11 int asn1_der_decoding_element(asn1_node * structure, const char * ele‐
12 mentName, const void * ider, int len, char * errorDescription);
13
15 asn1_node * structure
16 pointer to an ASN1 structure
17
18 const char * elementName
19 name of the element to fill
20
21 const void * ider
22 vector that contains the DER encoding of the whole struc‐
23 ture.
24
25 int len number of bytes of *der: der[0]..der[len-1]
26
27 char * errorDescription
28 null-terminated string contains details when an error
29 occurred.
30
32 Fill the element named ELEMENTNAME with values of a DER encoding
33 string. The structure must just be created with function asn1_cre‐
34 ate_element(). The DER vector must contain the encoding string of the
35 whole STRUCTURE . If an error occurs during the decoding procedure,
36 the * STRUCTURE is deleted and set equal to NULL.
37
38 This function is deprecated and may just be an alias to asn1_der_decod‐
39 ing in future versions. Use asn1_der_decoding() instead.
40
42 ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is
43 NULL or elementName == NULL, and ASN1_TAG_ERROR or ASN1_DER_ERROR if
44 the der encoding doesn't match the structure structure (*ELEMENT
45 deleted).
